Application filed April 7, 1916. Serial m'. 89,602.

This invention relates to certain improvements in molds for the manufacture of glass: ware and the like: and the olnects and na ture of the invention will be readily under stood by those skilled in the art in the light of the followingexplanation of the accompanying drawings illustrating- What I now believe to be the preferred embodiment or mechanical expression of my invention from among other forms, arrangements and constructions within the spirit and scope thereof. v

This invention relates to the production of glass bowls, vases, baskets or the like having upwardly extending or vertically disposed handles formed integral with the bowls or bodies of the auicles and joined thereto at diametrically opposite points. such articles being pressen in molds so formed for the passage of the plunger that the. article n' ill leave the mold with its handle deflected laterally. the article being then reheated and its handle bent. up to final uprightposition.

It an object of my presentinvention to produce a mold for the production of such articles of glassware wherein the mold will form and provide the handle forming cavity n'ithout the necessity of providing a core or other separate element.

A further object of the invention is to provide certain improvements in formation and arrangement for the production of a simple and exceedingly advantageous mold for the production of handled glassware.

T he invention consists in certain novel features in construction and in arrangement and formation as more particularly set forth and specified hereinafter.

Referring to the accompanying drawinejs, Figure 1, a side elevation of a mold cmbodying my invention. Fig. 2, is a vertical section taken in the plane of the line 2 2. Fig. Fig. 3. is a top plan. Fig. 4 is a. vertical section taken in the same plane as Fig. 2. and sluuviug the plunger and the pressed or molded glass article. Fig. 5, is a perspective of a "'ass artirlc producial by .irs the osition of the handle after the article has been reheated and finally completed. Fig. 8 is an ele ation of the opened niold showing the mold: cavity forming sides of the mold sections. j

In the particular example illustrated, the

mold comprises-a base 5. and two sections 1,

2. although I do not wish tb'liniit my invention to any particular number of sections,

and although I show these sections hinged together at 3, a nd provided with any suitable locking means 4. at their free ends, yet I do not Wish to so limitthe invention. These moldsections and the base provide a central vertical mold carity (lg-for eXteriorly shaping and forming the outer surface and top edge of the bowl or body of the glass article,

while a central vertical plunger 6, is mov- =able vertically through the upper port-ion of the mold and into said cavity to press the batch of molten glass therein to conform to the interior surfaces of'said cavlty and to.

shape and produce the desired surface f0rmation of the interior of the body-or bowl of the glass article. The sect-ionsl, i of the mold are peculiarly formed to provide a handle forming cavityb. at its opposite ends opening into diametrically opposite portions or the top of the mold cavity (1-, and this cavity F). is remote from the path traveled by the plunger and is formed by and between the meeting faces of the mold sections above the cavity a, and is so arranged that the molten glass under the pressureoii the plunger is forcibly driven into the cavity 7), to completely occupy the sameand conform to the surface and shape thereof. 7 4

In the present embodiment, the top wall of the mold cavity (ails formed by a horizontal annular overhangingcdge or shoulder 7. While the diametrically opposite ends 7), of the cavity Z), open through the surrounding Wall of cavity a. at the under side of the top Wall '7. so tl1at wall 7, overhangs the same. The cavity Z). extends upwardly from said ends 71 for a short distance and is then oil"- laterally from the central. longitudinal vertical plane of the mold.

The portion of the mold above the cavit-v o. is formed with a straight central vertical longitudinal bore 8. (usually cylindrical) at its upper end opening through the top of the mold and at lower end opening the top of the cavity of this bore is con-' "flentric withaud is surrounded nd to force or drive sufficient mpli'en rlw 1' v 1 n a,,1s forine'a by two slnul H loatecl (161)1'05510115 (1."111 f in funding or inhandle of the la s aruclv, will by located s l m h Slaw-1,118 fl .1.n me ninlfil 1" imtflg'l'al with the bowl v, and formed frmn 70 n ig batch ()f'glnbts as an %lgxg$l e same l vile-fill .6 Sa ens. v i I I s'a'mmnnula: eh i onS 1 suglznabeillmiizm i {W ll 220121 l and handle; and the fljgz can a; and nei tigally,
